This invention relates to an aeroplane. f It is particularly aimed to provide a novel, generallyiniproved and yet simple construction whereby an aeroplane or iying machine may hover, be eiiciently braked while in the air, and will be capable of rising in minimum space.

It is also particularly aime dto provide a4 20 ings illustrative of an operativeembo iment.,

Figure 1 is a plan view of an aeroplane constructed in accordancewith my invention;

Figure 2 is a side elevation thereof;

Figure 3 is a front elevation thereof;

Figure 4 is a rear elevation; Y 'Figure 5 is a sectional 'ew taken transversely on the line 5-5 of one of the planes of Figure'1;and 4 A.

Figure 6 is a plan view of a'modlfied form.

In carrying out the invention, 10 is a conventional fuselage equipped. with' usual or other rudder or tail steering and sustaining mechanism as at 11. The usual cockpit is at 41.2, and adjacentt-he same, guidewings 13 movable on horizontal pivots '14 by appropriate mechanism 15, are provided and which wings facilitate -guiding and steering generally. The fuselage is provided with grolin wheels or the equivalent as at 16.

Appropriately fastened to the fuselage 10 adj acentthe forward end is a skeleton superstructure or framework 17 which mounts any I desired number of motors or prime movers as 45 at 18, four being shown by way ofv example.l

It is obvious that these motors are of; any approved type.V Each of thesejmotqrs 1's -of the reversible type, with the reversing mechanism under control ofthe pilot in thecockplt 5 12,- in any suitableway. The central rnotor -propellers andl rear propellers.

' the planes if desired rather than -by the super 18 operates'shaft 19 to which front propellers 20 are keyed.l The outer motors .18 drive shaft 21 to which rear propellers 22 are keyed. Due tothe reversibility of the motors, the

propellers 22 may'bedriven in either direc 55' l tion desired.

A rod or shaft 23 is disposed in a. direction Q i A transversely of the fuselageand at the to of the superstructure 17'. Onlslrch: rod orsiiaft 23 and midway of their .'ends,a main lane 00 24 and'outer or side plane's 25 are journa ed or p1voted,being relatlvely' close to eachother. Means is provided whereby the plane 24 mayV be swung on the `axis of the shaft 23 indel pendently of the swinging of the plane 25 65 from the axis of that shaft. For example,

lthe plane 24 may have a'sprocket wheel 26 fixed thereto and a s rocket chain 27 trained thereover and associated with appropriate operating and lockin mechanism as at 28 79 under control of the p ot in the cockpit at 12. Llkewis'e each of the Aplanes '25 may have a gear wheel 29 ke .ed thereto and sprocket chains 30 trained t ereover. Sprocketlchains -30 are also trained over sprocket wheels 31 75.-

rigid with a shaft 32. having an operating crank as at 33 sothat the pilot may actuate the same in order to a'djustthe angle of the planes 25 independently of adjustment of the plane 24. Associated with the crank'33 is an 89 appropriate conventional locking mechanism such as 34; Y

Extending completely across the super'- structure 17 vintermediate the planes 24 and 25 are baiiles 35 of appropriate depth. These baille's `serve to avoid interference and sepa A rate the lines of air lcoacting with the front l It is to be understood that the baiiles may 'be carried by structure 17. j

At -the'rear of the plane 24, several small auxiliary planes 37 may be provided to facilitate steering and balancing. These planes are carried by'rods 38 suitably journaled in the framework 17.and are adjustable. through the actuation of 'appropriate chain vand sprocket mechanism, undercontrol Vo f the pilot from the vcockpit and 4as suggested at 190- 39, and which mechanism may be similar to said frame, sustaining planes three innum- -the'parts 26, 27,'28, or otherwise.

As a result'of the construction described, the planes 25 are adjustable in unison but 5 lindependeritlyof adjustment of the lane 24.

` they may be of ligleit This proves mosteficient in enab ing the rising of the aeroplane in minimum space or alightin therein as the planes will coact on a kite-like` principle `since `the propellers 18 and 22 force air thereunder when such propellers are at an angle when (the aeroplane is rising. At proper adjustment,

the aeroplane will be held practicall braked against forward movement by t e propellers l22 which in such instance operate in reverse forcing air ahead while the propellers 18 are forcing air to the rear. Under such conditions the baie plates 35 keep the air current separate or from interfering with each other so that maximum efficiency is attained both for lifting and for carrying. Particularly when the rear propellers 22 are reversed, they act as a brake causing the aeroplane to hover or stop in a short distance or remain substantially stationary in the air without falling.

It is to be understood that the means illustrated for accomplishing the different functions and ends has been detailed b`y way of example only and that no limitation thereto is to be. implied since various changes may be made and equivalent views without departing from the spirit and scope of the invention.

ber mounted to swing on said rod to different .positions of adjustment, propellers at the rear of the outer planes, a propeller at the front ofthe intermediate plane, motor mechanism on `the frame to operate said Propellers,

A means operable by a pilot from the cockpit to The braking feature may well be used on Y aeroplanes of the type using a rotatin propeller for rising straight up in the air and alsowith present ordinary wings when used as braking or stopping' short only'. For instance a present type of stationary aeroplane 'is suggestedin plan in Figure 6. ReferringA to that figure the main plane of the aeroplane is shown at 50 having at 51, a suitable lifting propeller driven by a shaft 52 vertically disposed. Coacting therewith, are forward pro ellers 53-and rear propellers 54 correspon ing respectively with the propellers 18 and-22, being reversible and driven from any suitable source of power. j

It may be mentioned that the planes orl 'wings 24 and 25 may be of any appropriate constuction, that is of a light wood or metal framework covered with canvas or v metal or otherwise. As -well they may. reenforced by framing" as at 40.
